stance, is used in the manufacture of composite cry of the web. Each annular flange has the enlarged free end portion F which terminates in the radial flange G. The annular insert C has the outer radial portion H which is located between the radial flanges G, the oppositely extending axial portions I which are preferably tapered toward their edges and closely fit within the enlarged free end portions F, and the inner radial portion J which is preferably of less width than the outer radial portion.

The holder I2 comprises the head 2| and the outer and inner chuck sections 22 and 23, respectively, carried by the head. The outer chuck section comprises the annular body 24 and the concentric ring 25 mounted atthe inner side of the body. The body is fixedly secured upon the outer ends of the rods 26 which extend transversely from and are fixedly secured at their inner ends to the head 2i. The inner chuck section comprises the plate 2'! and the concentric ring. 28 mounted at the outer side of the plate. The plate is slidably mounted upon the rods 28; The rings 25 and 28 are constructed to encircle the annular flanges E of the shells A and B, respectively, and to abut the radial flanges G of the shells. To reduce loss of heat from the annular flanges, the rings are formed with peripherally spaced axial ribs or lands for engaging the annular flanges. The annular body 24 and the plate 21 are constructed to conform to the contours of the radially outer portions of the webs D of the shells A and B, respectively. With this construction, the holder is adapted to directly clamp the radial flanges at the free ends of the shells against the annular insert, to engage and hold the annular flanges of the shells circular and to predetermined size and to true the annular flanges of the shells if they should happen to be out of round when the work is inserted into the holder.

29. is an outer hollow shaft in axial alignment with and connecting the holder I2 and the cylinder l3, the head 2| of the holder being mounted on the outer end of the shaft and the outer end of the cylinder being mounted on the inner end of the shaft. The shaft is journaled intermediate its ends in the bearing 39 upon the outer end of the support I5. 3| is a shaft in axial alignment with the shaft 29 and located at the inner end of the cylinder l3 and journaled in the bearing 32 upon the inner end of the support IS. The

shaft 3|, as shown, is an integral part of' the pulley l9. The two shafts 29 and 3| support the sub-unit comprising the holder l2 and the cylinder l3 in the support I5 and rotate with and also provide for rotation of the sub-unit about the axis common to both-the holder and cylinder.

33 is a second hollow shaft axially slidable within and guided by the shaft 29. The shaft 33 is adapted to be reciprocated by the piston 34 which is reciprocable in the cylinder [3. A suitable medium under pressure, preferably compressed air, may be admitted to and exhausted from either side of the piston through th'e pipes 35 and 36 under the control of the valve 31, the exhaust from the valve being through the pipe 38. The valveis adapted to be manually operated and is of standard construction manufactured by a well known manufacturing concern. The connection between the shaft 33 and the piston 34 comprises the piston rod 39, the stud 40 threaded into the outer end of the piston rod and having the integral collar 4| abutting the inner end of the second shaft 33, and the pin 42 which extends through the outer end of the stud and the inner end of the second shaft. The arrangement is such that the second shaft is positively reciprocated in both directions and in its outer direction th'e pin is relieved from shear by the collar upon the stud. Fixed upon the outer end of the second shaft 33 is the central abutment 43 upon which is mounted the plate 21 of the inner chuck section.

44 is a third shaft which is axially slidably mounted in and guided by the second shaft 33. The third shaft has fixedly secured to its outer end the pilot abutment 45 and as shown, is provided with the inner and outer collars 46 and 41 for slidably engaging the second shaft 33. 48 is a coil spring within the second shaft and located between the stud 40 and the inner collar 48 for yieldably urging the third shaft axially outwardly. It will be noted that the central abutment 43 is adapted to engage the outer collar 41 to limit the outward movement of the third shaft. The pilot abutment 45 is adapted to receive the web of the inner wrought metal brake drum shell, the pilot portion being adapted to extend through the central opening in the web and the abutment portion being adapted to abut the adjacent portion of the web.

With this constri'iction it will be seen that when the medium underpressure is admitted to the inner end of the cylinder 13 by manually manipulating the valve 31, the piston 34 is forced outwardly and moves the inner chuck section 23 toward the outer chuck section 22. Also, when the medium under pressure is admitted to the outer end of the cylinder and the medium under pressure at the inner end of the cylinder is permitted to exhaust, the piston will be moved inwardly and move the inner chuck section away from the outer chuck section a distance such that the chuck sections and also the pilot abutment completely release the work. To assure disengagement of the work, suitable ejector rods 4., as shown in Figure 6, are engageable with the web of the inner shell when the inner chuck section is moved inwardly. The ejector rods extend transversely from and are secured to the head 2| of me holder and are adapted to extend through the plate 21 of the inner chuck section.

50 is a pouring spout for each casting unit carried upon the arm 5| which is pivotally mounted upon the stationary arm 52 secured to and carried by the support l5. Each pouring spout has the body portion 53 and the arcuate guide portion 53' leading from the body portion. Both the body portion and the guide portion are open at their upper sides and both are provided with the partition wall 54 extending upwardly from their bottom walls midway between their side walls. The free end of the guide portion is open and the free end of the partition wall is adapted to register with the end of the inner radial portion J of the annular insert when the pouring spout is in operative or pouring position so that the liner material, which is preferably molten cast iron, will be poured into the shells on opposite sides of the inner radial portion of the insert. The size of the guide portion and its radius of curvature and also the position of the pivotal connection between the arms 51 and 52 are such that the guide portion may be readily swung into the central opening in the web D of the outer hub shell A when the work is clamped in the holder. .55 is a measuring ladle pivotally nounted upon the body portion 53 of each pourmg spout to be swung upwardly to pour the liner material therefrom into the body portion of the pouring spout. The measuring ladle is provided with the central partition wall 58 for securing the desired amount of liner material to.

be poured into each brake drum shell. As shown, the measurin'gladle is adapted to be tilted or swung by means of the lever 51 which is fixedly secured to one of the pins forming part of the pivotal connection between the measuring ladle and the pouring spout.

For the purpose of swinging each holder from its substantially horizontal casting position to its substantially vertical work receiving position, a cam is engageable with the support of each casting unit. As shown, 58 is a stationary cam beyond the periphery of the table 3 and 5.9 is a roll upon the support l5 of each casting unit engageable with the cam during the rotation of the table. The face of the cam engaged by the roll is arcuate with respect to the table and is curved upwardly and twists from the front end to the rear end of the cam, the twist being through an angle of substantially 90 from an upper approximately horizontal position to'an inner approximately vertical position. Each casting unit is unbalanced about its pivots and when released by the cam 58 will swing by gravity from its substantially vertical position to its substantially horizontal position. The return of the casting unit to its substantially horizontal position is cushioned by a dampening device comprising the cylinder 69 pivotally connected to a furcation ii of the base I1 and a cooperating piston 69' pivotally connected to the support I5.

To assure each casting unit remaining in its substantially horizontal casting position during the casting operation, I have provided the holddown stationary cam 6| which is located beyond the periphery of the table 9 and is arcuate with respect thereto. This cam is engageable with the roll 59 after the casting unit has been swung down from its substantially vertical position to its substantially horizontal position upon release from the cam 58. Both the front and rear ends of the cam 6L are preferablycurved upwardly, the major portion between the ends being'horizontal. During the time the roll 59 is in engagement with the horizontal portion of the cam,

the pouring spout is swunginto casting position and the molten liner material is poured into the pouring spout. However, before the liner material is poured into the pouring spout, the electric current through the manually operable electric switch 52 and the holder 12 is brought up to the desired R. P. M.

Each furnace unit 2 comprisesthe upper and lower furnace sections 88 and 94, respectively.

' The lower section is supported upon the columns No. 306,418, filed November 27, 1939. The upper section is adapted to be raised and lowered with respect to the lower section and, as shown, the upper section is carried by the diametrically opposite supports 69 which are guided by the col-. umns 19 extending upwardly. from and mounted on the table. As shown; the supports 59 are tu-,.

bular and are sleeved over the columns 10. H

is a cross bar sleeved over and guided at its ends,

by the columns 19 and carrying the supports 59. I2 is a pitman pivotally connected at its upper end to the middle of the cross bar TI and pivotally connected at its lower end to the arm 18 which is fixed upon the inner end of the shaft II. The shaft extends substantially radially of the table 8 and is journaled in the bearings upon the table and it has secured to its outer end the crank I8 having the roll 11 engageable with the sta- 20 end the work receiving yoke 88. The arm is pivof the lever 84, the lower end of which is fixed otally connected at its innerend to the upper end no link extending substantially radially of the table and pivotally connected at itsinner end to the arm 99 secured to the shaft 85 and at its outer end to one arm of the bell crank 9|. The bell crank is pivotally mounted upon the table near its periphery to swing horizontally and the other arm of the bell crank carries the roll 92 which is engageable with the stationary cam 98 peripherally beyond the table. The cam has the inclined cam face 94 at its front end which upon being engaged by the roll 92 compels the arm 82 to move forwardly from its normal position in registration with the furnace. The cam also has the reversely inclined cam face 95 following the cam face 98 and permitting the arm 82 to move 48 rearwardly to a position in which the yoke 98 is located radially inside the work holder when in substantially vertical position to clear the work holder. The cam also hasthe arcuate cam face 98 following the cam face 95 and adapted to hold 50 the yoke in a position clearing the work holder tric motor H is connected to a source of elecuntil it has been swung from substantially vertical position. The cam further has the cam face 91 following the cam face 99 and adapted to cause the arm to move forwardly to position th yoke 65 in work receiving position adjacent to the stationary platform 98. The rear end of the cam is rounded away from the cam face 91 so that as the roll 92 rides over the rear end the yoke returns to its normal position centrally of the associated furnace. This normal position is determined by thestop 99 upon the table 3 engageable with the weight 890 at the end of the arm I0! upon the lever 84. The weight I00 constantly exerts a force on the transfer device sufficient to return it to its normal position when it is under the control of the cam 93."

- To provide for disengaging thework from the holder after the work has been lined, I have provided the stationary cam I02 peripherally beyond 7 the table and engageable with the outer end "or,

more properly speaking, the clamping nutat the outer end of the lowermost rod 26 of the holder to cause the holder to turn as the table is being rotated to assume a position such that the two lowermost rods 26 will'be at the same elevation.

As shown, there are three rods 26 and sufficient space is provided between adjacent rods to permit the work to freely pass therebetween. After the two lowermost rods have been compelled to assume the same elevation, the work is free to drop without interference thereby when the inner '.chuck section 23 of the holder is moved inwardly.

To turn the holder so that the rods 26 will not interfere with th transfer of the work from the furnace to the holder-i, I have provided the stationary cam I03, as shown in Figures 1 and 9, located beyond the periphery of the table and adapted to engage the outer end or, more properly speaking, the clamping nut at the outer end of the uppermost rod 26 of the holder to compel the holder to turn as the table is being rotated to assume a position with the two uppermost rods at the same elevation. As a result, it will be seen that when the casting unit is swung from horizontal position to vertical position none of the rods 26 of the holder will interfere with the passing therebetween of the work by the work transfer device.

Each pouring spout 50 is adapted to be swung to operative and inoperative positions by means of the link I04, the lever I and the fluid pressure device I06. The link I04 is pivotally connected at its outer and inner ends respectively to the free end of the arm 5| and the upper end of the lever I05. The lever is pivotally mounted intermediate its ends on one of the furcations of the base if and pivotally connected at its lowor end to the piston rod I01. The fluid pressure device is preferably an air cylinder in which the piston is connected to the piston ,rod I01. The construction is such that after the molten liner material has been poured with the spout in operative position, compressed air is admitted to the inner end of the cylinder by manually operating the valve controlling the same. The compressed air forces the piston outwardly and through the piston rod, lever, link and arm swings the pouring spout to its inoperative position clearing at least the inner face of the outer chuck section of the work holder. As a result, the pouring spout cannot interfere with the disengagement of the work from the work holder after the work has been lined. The construction is also such that after the work has been disengaged from the work holder and before the work to be lined has been inserted into the work holder compressed air can be admitted to the outer end of the cylinder and the air at the inner and per-- mitted to exhaust to return the pouring spout to operative position. This can be done because the pivot between the lever I05 and a furcation of the base I! is, located at such a distance below the pivot connecting 'the support I5 and the furcations of the base II that when the casting unit is swung from substantially horizontal position to substantially vertical position the pouring spout is automatically swung to inoperative position so that it will not interfere with the insertion of the work to be lined into the work holder.

To compensate for vertical movement of the inner end of the arm 82 during longitudinal movement of the arm, it is formed with the cam surface 82' engageable with the roll 88 so that the yoke 83 upon the arm will normally be moved through a horizontal path.

In operation, assuming the table 3 to be rotatin in the direction indicated by the arrow in Figure 1 and the casting unit to be leaving the stationary cam I03. at which time the inner and work cease rotating.

chuck section 23 is in its innermost position, the cam 58 upon being engaged by the roll 59 swings the casting unit from horizontal position to vertical position. As the casting unit is approaching its vertical position, the cam 18 upon being engaged by the roll 11 causes the upper section 63 of the furnace 2 to raise. After the upper furnace section has been raised, the front end portion 94 of the cam 93 upon being engaged by the roll 92 causes the arm 82 to be advanced or moved forwardly from its normal position with its yoke 83 centrally within the furnace to a position registering the work carried by the yoke with the inner chuck section 23 of the holder, the chuck section at this time being below the outer chuck section 22. After the work has been registered with the inner chuck section, the yoke 83 is lowered by slightly lowering the upper furnace section 63. This slight lowering is accomplished by forming the cam 18 with the raised portion I08 which holds the upper furnace section in its slightly lowered position until the yoke has been retracted to clear the holder of the casting unit. The retractingis accomplished by the weight I00 and permitted by the cam face of the cam 93. The cam face 96 of the cam 93 holds the yoke in this position during which time the work holder swings downwardly to its horizontal position. As the roll rides. over the cam face 91 of the cam 93' the yoke is moved outwardly to a position adjacent the platform 98 at which time the work to be lined can be moved onto the yoke. As the roll rides over the rear end of the cam 93, the arm 82 and its yoke and the work thereon are moved inwardly to normal position with the work centrally of the lower furnace section 64, after which the upper furnace section 63 is lowered to its normal position by reason-of the roll leavin the cam 18. After the work has been moved to a position clearin the work holder, the work which was transferred to the work holder is sections of the work holder by manually or autoclamped between the outer and inner chuck matically manipulating the valve 31. Then the casting unit is returned from vertical work receiving position to horizontal casting position by gravity after the roll 59 has left the cam 58. Then the roll 59 engages the cam 6| to hold the casting unit in horizontal position, after which the electric switch 62 is manually or automatically operated to start the electric motor, which in turn rotates the holder and the work carried thereby. The pouring spout at this time is in inoperative position and the molten iron at a temperature of approximately 2900 to 3000 F. has been placed in the measuring ladle. When the desired R. P. M. of the work has been secured, the ladle i manually or automatically tilted to pour the molten iron into the pourin spout which directs the molten iron against the annular flanges of the two brake drum shells of the work. After the pouring, the pouring spout is moved to inoperative position. The rotation of the work is continued through approximately 180 of rotation of the table to give the molten iron sufficient time to cool and solidify to the desired extent. When the table has rotated through this zone, the electric switch 62 i manually or automatically operated to disconnect the electric motor I4 from the source of current and the holder Then the cam I02 causes the work holder to rotate to place two of its rods 26 in lowermost and horizontal position, if the holder is not already in-this position, after which the valve 31 is operated to move the inner chuck section 23 of the holder inwardly to release work holder, the cam I03 then compels the holder to rotatelto assume a position with two of its rods lfiuppermost andhorizontal, the casting unit then being in position to be tilted from horizontal position to vertical position. Also, after the work has been released from thework holder the pourin spout can be returned from its inoperative position to its operative position. It will be noted that the work i beinglheated from the time the upper furnace section is lowered to operative position until it is raised toinoperative position, or throughan angle of approximately 270 of rotation of the table. This provides for sufficient time interval toheat the work to approximately 1300 F. without subjecting it to an excessive temperature.
